Answer / suman agrawal

Using comp, the value will be stored in binary format.
The allocation in number of bytes is based on the number of
digit the variable use:

No. of digits Bytes
1-4 2 bytes
5-9 4 bytes
10-18 8 bytes

Answer / guest1

When you use COMNP Items, the internal storage stuctur of
the value is different. And also the storage occupied by a
COMP variable is less than the zoned variable [9(9)}.

Answer / garry

I am not sure about previous explanation, however before that all explanations are valid.

One thing should be clear in our mind that COMP usage is good but it can not be displayed simply, it will store in binary format, so we need to convert it in to ZD, if displaying in SYSOUT or writing to a file.

Please let me know if I am wrong.
Thanks

Garry

Answer / prathif

numeric data refered by pure binory storage format. it will
take half word and full word.
each character recognized by one character. total number of
chracter equal to size of word is called normal variable

Answer / naveen kumar.s

The value assigned to comp variable is stored in binary
format.The memeory allocation is also different.
For example,
77 A pic 9(8).
77 B Pic 9(8) comp.

Here,'A' occupies 8 bytes.whereas,'B' occupies 4 bytes only.

No.of Digits Bytes occupied

1-5 2
5-11 4
12-18 8
